Abstract: This invention relates to the neural interface comprising one or more electrode-coupled microchannels. Each electrode-coupled microchannel comprises a microchannel for accommodating regenerating nerve axons; and one or more electrodes exposed to the interior of said microchannel. The one or more electrodes may comprise (i) a stimulation array suitable for generating an extracellular stimulus current which induces an action potential in an axon in the microchannel; and/or (ii) a recording array which detects an extracellular signal in the microchannel indicative of an action potential in an axon in the microchannel. Interfaces as described may be useful in blocking pain, treating misrouted motor nerves; repair or treating nerve injury; or controlling or providing sensation and/or proprioception from a prosthesis.
